| Worm-Drive Clamp | A screw turns a perforated band to tighten or loosen the clamp. | General-purpose plumbing, automotive hoses, and many low- to moderate-pressure connections. | Adjustable, reusable, and widely available in a range of sizes. | Choose a size that places the hose within the clamp’s stated range. Check that the band and housing suit the environment, and avoid overtightening, which can damage the hose. |
| Smooth-Band Fuel-Injection Clamp | A screw tightens a band with a smooth inner surface and rounded edges. | Fuel-injection and other soft or thin-walled hoses where a conventional perforated band could mark the hose. | Spreads clamping force more evenly and reduces the risk of the band’s slots cutting into the hose. | Use a clamp designed for the hose and service conditions. Confirm fuel compatibility and the manufacturer’s specified size and tightening guidance. |
| T-Bolt Clamp | A bolt and nut draw together a heavy-duty band, typically with a bridge over the bolt area. | Large-diameter or reinforced hoses, including some charge-air, industrial, and heavy-vehicle connections. | Provides a strong, secure clamping arrangement and is available in robust constructions. | Match the clamp’s size, construction, and rated performance to the connection. It may be excessive for small or delicate hoses; do not assume all T-bolt clamps have the same pressure capability. |
| Spring-Band Clamp | A preformed spring-steel band contracts around the hose when installed. | Factory-style automotive and small-appliance hose connections, particularly where space is limited. | Compact and quick to install with suitable pliers; its spring action can accommodate some hose movement. | Use the correct diameter and installation tool. Check corrosion resistance and compatibility with the hose and operating temperature. |
| Constant-Tension Spring Clamp | A spring-loaded design maintains force as the hose expands or contracts. | Cooling-system and other connections subject to temperature changes and hose compression set. | Can help maintain a seal through thermal cycling without routine screw adjustment. | Confirm the clamp is specified for the hose diameter and application. It is not a substitute for a clamp with an appropriate pressure or temperature rating. |
| Ear (Crimp) Clamp | One or more raised ears are compressed with a tool to reduce the band diameter. | Automotive, appliance, and industrial assemblies made for a fixed hose-and-fitting combination. | Low-profile, compact, and tamper-resistant after installation; suitable for repeatable production assembly. | Installation generally requires a dedicated crimping tool, and removal usually destroys the clamp. Select the correct size before crimping. |
| Wire Clamp | Formed wire tightens around a hose, commonly by means of a screw or bolt assembly. | Some large-diameter rubber hoses and specialized or legacy equipment. | Its wire construction can suit certain hose profiles and larger connections. | Check that the wire shape distributes force appropriately for the hose. It is not interchangeable with a band clamp in every application. |
